Title

Structure of GeS2 Glass by Neutron Diffraction with Isotope Substitution

Abstract

The method of neutron diffraction with isotope substitution will be used to measure the full set of partial structure factors for the prototypical chalcogenide glass GeS2, which is used in the fabrication of optoelectronic and non-volatile memory devices. The results will be used to differentiate between the various models that have been proposed for GeS2 glass, a necessary first step in identifying its structure-function relationships. The results will also be used in the search for suitable protocols for simulating the structure of GeS2 glass by using first-principles molecular dynamics simulations, and will provide a firm basis for interpreting the structural transformations that occur to GeS2 glass under high pressure and temperature conditions.
